A Moving Field Inductive Power Transfer (MFIPT) system for wireless inductive power supply of electric vehicles on the road is described. To minimize losses only those primary coils located below the secondary coil of a vehicle are excited. The dynamics, the power balance of the MFIPT system, and the costs for the implementation of the system are discussed.
Electromagnetic Wireless Power Transmission (WPT) can be realized by using resonant coils coupled via their magnetic fields; in order to extend the range for power transmission, it is convenient to introduce additional relay elements. By considering a simple, yet rigorous, equivalent network, we derive a general property which is useful for the design of wireless power transfer networks with relay...
Electromagnetic Wireless Power Transmission (WREL) can be achieved by using resonant coils coupled via their magnetic fields; these resonant coils must be, in addition, properly coupled to the source and load. By using a simple, yet rigorous, equivalent network, we introduce a computer-aided design procedure to reach the maximum efficiency for a given value of the resonators quality factor and for...
